Light Duty – ISO Metric Series

(Solid Green)
Loads are shown in Newtons.

Efficient Operating Range is 25% to 35% deflection of free length. Maximum deflection is 35%; Long Life deflection is 30%; Optimum Life deflection is 25%. Deflection beyond this Efficient Operating Range could result in premature spring failure. Travel to Solid is a reference dimension only and should never be approached during use.
